... I obviously haven't been around fandom long enough, because I have absolutely no idea who RP is.

I'm only in a couple of games at the moment: Age of Glory (http://www.ageofglory.net) (non-HP) and Hogwarts (http://s15.invisionfree.com/hsww/) (HP, original characters), both of which I run. I actually wouldn't mind joining a journal-based game or two, but I have to get caught up in those two first ...
